Shimizu Seisakusho (2012-2014)
I worked at Manufacturer industry as engineer for two years three months in Shimizu Seisakusho, a customer of Honda H-One, Suzuka City, Japan. There, I do welding operation, press machine maintenance and quality control for metal part components. From all I learned there, I am interested to implement 3S (seiri, seiton, seishou) to organize workplace as well as Kaizen (continous improvement) and hanzei (self evaluation) to improve productivity.

Technical Skill/Services:

Scientific Computing
Currently I am developing my skill on scientific computing with Matlab, GNU/Octave, Python and C/C++. You can consult to me your problem with those software related to science and tech (physics, biology, chemistry, machine learning, signal/image processing, and others). I will implement your idea to program as much as I can. Partially, I am also experienced on Unix/Linux command line, Git, Mercurial, Gnuplot, and other scientific software/tools.

Content writer
I have experienced in writing English article for web content, internet marketer, product review and or other purposes. If you want to use my service to write article in English or to ask me to be re-writer/copy writer of an article, just contact me via email or social media I have provided.

Language skill: English
I am also very happy if someone ask me to be partner on his/her English study. Whatever subject you want to study: grammar, conversation or just to level up your English level, I will be ready, coz I am also still learning in English.
The cost/fee..? If you life in Japan, just pick me or provide transportation to your home or the place to study English (even though in Okinawa, I will go..:D), and of course the food and accommodation if I need to stay. That's enough for me. If you pay more, I am very welcome ... :D

I am Ubuntu Linux user for more than 3 years. Although I am not geek, I can share what I learned, how-to install and fix problem on Linux system as long as I can solve it. You can read my post about my experience, solved problem, unsolved problem, tips and trick on GNU/Linux here. How to invite me to share my Linux experience ? Just go to café with me, and treat me a cup of coffee, and we open our Laptops while drinking coffee. Then, we learn about unity, dash, lens, libreoffice, apt-get, libreoffice (writer, calc, impress), and.... CLI (command line interface) on terminal (if you want). Just a cup of coffee? Yes. No beer please...
